Preface Existing views on geodynamics (recharge, migration, discharge) of fluids at deep layers of petroliferous basins are summarized. The infiltration and elision theo- ries explaining development of fluid pressures in deep formations are called into questionbasedonquantitativeestimatesavailableforsomeartesian(petroliferous) basins.UsingtheWestSiberian,Pechora,Terek-Kuma,Bukhara–Karshi,andother petroliferousbasinsasexamples,thestratum-blockstructureofdeepformationsis substantiated for stratified systems of platform in inter- and intramontane depres- sions. It is shown that petroliferous reservoirs at great depths are characterized, regardlessoflithology,bylargelyfissure-relatedcapacityandpermeability(clayey rocksincluded)changeableinspaceandthroughgeologicaltime.Muchattentionis paid to development of abnormally high formation pressures. Peculiarities in heat andmasstransferatdeeplevelsareconsideredfordifferentregions.Theenergetic formation model substantiated for deep fluids explains different anomalies (baric, thermal,hydrogeochemical,mineralogical,andothers)atdeeplevelsofplatforms. Based on hydrogeodynamic considerations, the theory of oil origin and formation ofhydrocarbon fieldsisproposed.Thebookisofinterestforoilmen,hydrogeolo- gists, geologists, and specialists dealing with prospecting of petroliferous deposits as well as industrial, mineral, and thermal waters in deep formations of stratified sedimentarybasins. vii Contents 1 ExistingViewsonFluidodynamicsinPetroliferousFormations . . 1 References . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 2 InvestigationMethodsofDeepFluidodynamics . . . . . . . . . . . 15 2.1 MethodsofFormationPressureReducing . . . . . . . . . . . . 16 2.2 AssessmentofDirectionsofDensity-VariableFluid Flowsbythe“FiltrationForce”Method . . . . . . . . . . . . . 25 2.3 TheDirectMethodofAssessingDensity-VariableDeep FluidFlowDirections . . . . . . . . . . . . . . . . . . . . . . 26 2.4 ModelingMethodsintheStudiesofDeepFluidFlows . . . . . 27 2.5 CompilationMethodsofRegionalPotentiometricMaps forPetroliferousFormations . . . . . . . . . . . . . . . . . . . 30 2.6 MethodsofCompilingHydrogeodynamicMaps . . . . . . . . 33 2.7 Investigation Methods of Temperature andConcentrationFields . . . . . . . . . . . . . . . . . . . . . 34 References . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 35 3 Role of Regional Infiltration Recharge Sources intheFormationofDeepFluidsandPetroliferousBasin HydrodynamicZoning . . . . . . . . . . . . . . . . . . . . . . . . . 37 3.1 RoleofPetroliferousBasinPeripheryinRecharge ofDeepFluids . . . . . . . . . . . . . . . . . . . . . . . . . . 37 3.2 HydrodynamicZonesinPetroliferousBasins . . . . . . . . . . 41 References . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 45 4 ElisionRechargeandPaleomigrationofDeepFluids . . . . . . . . 47 References . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 56 5 GenesisofAbnormallyHighFormationPressures. . . . . . . . . . 59 5.1 The Relaxation Period of Abnormally High FormationPressures . . . . . . . . . . . . . . . . . . . . . . . 61 5.2 Possibilities for Development of Fluidodynamic HorizontalBoundariesinClayeySequences . . . . . . . . . . . 63 5.2.1 Variant1 . . . . . . . . . . . . . . . . . . . . . . . . . 67 5.2.2 Variant2 . . . . . . . . . . . . . . . . . . . . . . . . . 67 ix
